Description
Technical field
The present invention relates to one kind having highly-breathable and anti-PM2.5 masks, mask or mask, for preventing in air
PM2.5 grades of fine particles, dust, bacterium, virus suck in human body.
Background technology
PM, full name in English are particular matter, as particulate matter.PM2.5 refers to that diameter is less than or waits in air
In 2.5 μm of particulate matter, also referred to as lung particulate matter.Its grain size is too small to be not easy to be stopped by respiratory tract, is inhaled into meeting after human body
It is directly entered bronchus and alveolar, interferes the gas exchanges of lung, and causes other diseases.PM2.5 grain sizes are small simultaneously, surface
Easily rich in a large amount of toxic, harmful substance and atmospheric residence time is long, fed distance is remote, thus is caused to human body a variety of strong
The threat of health.
With the rapid growth of China's economy, the PM2.5 granule densities in multiple big and medium-sized cities air are higher, seriously endanger people
Body health.To prevent air pollution, generally use wearing mask protection, but existing most of mask for PM2.5 (in air
Diameter is less than or equal to 2.5 microns of suspended particulate substance) there is no protection effect, do not have sterilization sterilizing function yet.
Currently, it is all that the non-woven fabrics with certain filter capacity is added wherein to have the mask of protection PM2.5 in the market,
Leaf membrane etc..But for filtering material, separating property and Air permenbility are a pair of conflicting parameters.That is filtering accuracy
Its higher effective aperture is smaller, and Air permenbility is smaller.And its poor effective aperture of filtering accuracy is larger, Air permenbility is also big.For sky
For PM2.5 in gas, grain size is smaller, it is desirable that the filtering accuracy of filtration fraction is high, and aperture is smaller, so applied to removal
The Air permenbility of the filtering material of PM2.5 is often all smaller.For mask, the effective filtration area of flat separation material
Smaller, gas permeability is inadequate, the feeling for causing user to feel oppressed.Under same volume, hollow fiber form filtering material it is effective
Filter area is 10-100 times of flat filtering material.Hollow fiber form capillary-pipe film is separated by filtration pore-size distribution in capillary
On periosteum tube wall, convenient for encapsulation.Therefore, selecting has hollow fiber form capillary-pipe film as filtering material, can significantly carry
The gas permeability of high mask eliminates the sense of feeling oppressed of user.

Specific implementation mode
Embodiment 1-3 is shown in Fig. 1,2,3 and 4：The mask of the present invention includes 3 part of filtering chipware, with closely sealed frame 6 (by outer
The endless elastomer sealing ring being equipped in the middle part of cover inner surface is constituted) outer cover 7, carry the gas-guide tube 5 of check valve 4, mask frenulum
Fixation is fitted to (face) on the face.Filtering chipware 3 is mainly made of hollow fiber form capillary-pipe film 2, according to use occasion to mistake
The requirement for filtering precision and Air permenbility, selects the hollow fiber form capillary-pipe film 2 of different filtering accuracies, different length and radical.It crosses
Filter core part 3 can be made of one (embodiment 2) with frenulum (embodiment 1) or with outer cover 7, or be worn as independent filter element
(embodiment 3) with it.
The action principle of the filtration fraction is as follows：
The hollow fiber form capillary-pipe film 2 for being cut into certain length is a branch of with two end fluid sealant cast, and it is encapsulated in two
In the container 1 of end opening, two end outside wall surfaces of hollow fiber form capillary perineurium and two open end internal faces of container seal
Glue airtight connection, shell of tank are provided with stomata, see Fig. 1.In certain space, since capillary-pipe film (2) outer diameter is in 0.1-2.5
Between millimeter, the more flat or common tubular type of loading density (diameter is more than 5-10 millimeters) filtering material is 10-100 times big.
The mask of flat filtering material, 9000 square millimeters of effective filtration area；A diameter of 8 millimeters of tubular filter material,
Its effective filtration area is 19600 square millimeters.And hollow fiber form capillary separation material in the present invention is used to prepare filtering
Part, effective filtration area can reach more than 300000 square millimeters.For flat and tubular filter material,
Filtration fraction in the present invention abundant can cross air filtering, generate pure air for the happy breathing of people.
It is connected with user mouth and/or nasal cavity by gas-guide tube 5 using 2 inner cavity of capillary-pipe film for filtering chipware 3, is held
The directly logical air of stomata is connected on device 1.With human body respiration, air sucks container from filtering 3 container of chipware, 1 shell in air
Region that is interior, entering film inner cavity (see Fig. 1) across 2 hole of capillary-pipe film and surrounded to the closely sealed frame of 7 inner surface of outer cover 6 through gas-guide tube 5
For breathing.Since aperture ratio PM2.5 particles are small on 2 tube wall of hollow fiber form capillary-pipe film, PM2.5 particles are effectively blocked in
Outside capillary-pipe film.
Although the present invention gives embodiment to hollow fiber form filtering capillary-pipe film filtering chipware, this field it is general
Logical technical staff is appreciated that.Embodiment is changed in the case where not departing from the principle of the invention and objective, change, is replaced
With deformation etc. masks or mask etc., such as can be used in construction worker, sanitationman, winnow peasant, coal mining, sandstone factory work
The sterile working arranged is done by people, marble exploitation person, asthmatic patient, Chinese style and Western-style cook and millet cake teacher, food factory
Such as soy sauce, vinegar, monosodium glutamate sterile working, cold chain distribution packaging, the division of respiratory disease of hospital, pulmonary tuberculosis and hepatitis infection disease ward
Deng still falling within scope of the presently claimed invention.
